Cisco Communication Media Module for Catalyst 6500 Series Switch and Cisco 7600 Series Router Installation and Verification Note
Accessing the Port Adapter Ports
From the module command-line interface (CLI), you identify each port adapter by
interface_name
followed by
slot_num
/
port_num
. For example, to configure the first port on a 6-port T1 port adapter that
is installed in slot 2, specify
T1 2/0
. For the second port, specify
T1 2/1
, and so on.
